IP Traffic in 2017: 1.4 Zettabytes

Based on observations made at ISPs around the world, Cisco forecasts that by 2017, annual global Internet traffic will rise to 1.4 zettabytes (that’s 1021 bytes), compared to “just” 528 exabytes (1018 bytes) in 2012. At this time 80 to 90 percent of all consumer Internet traffic will be some form of video, but other sources contributing to the rise include machine-to-machine communication and the proliferation of mobile devices.

Peer-to-peer file sharing would make the Internet far more efficient

When the COVID-19 pandemic erupted in early 2020, the world made an unprecedented shift to remote work. As a precaution, some Internet providers scaled back service levels temporarily, although that probably wasn’t necessary for countries in Asia, Europe, and North America, which were generally able to cope with the surge in demand caused by people teleworking (and binge-watching Netflix). That’s because most of their networks were overprovisioned, with more capacity than they usually need. But in countries without the same level of investment in network infrastructure, the picture was less rosy: Internet service providers (ISPs) in South Africa and Venezuela, for instance, reported significant strain.

But is overprovisioning the only way to ensure resilience? We don’t think so. To understand the alternative approach we’re championing, though, you first need to recall how the Internet works.
